The highly obscured region around PKS 1343 – 601 – I . Galactic interstellar extinctions using DENIS galaxy colours
The highly obscured radio-bright galaxy PKS 1343 – 601 at Galactic coordinates of (l, b) = (309. ◦7,+1. ◦8) has been suspected to mark the centre of a hitherto unknown cluster in the wider Great Attractor region. As such it presents an ideal region for a search of galaxies in the near-infrared (NIR) and an in-depth study of their colours as a function of extinction. A visual search of a ∼30 squ...
متن کاملDenis Detections of Highly Obscured Galaxies in the Area around Pks 1343 – 601
We present results of a search for galaxies around the highly obscured giant radio galaxy PKS1343– 601 using the near-infrared DENIS survey. We compare our findings with surveys in the B-band, at the 21 cm line emission, and with 2MASS. Recession velocities of galaxies in this area suggest a low-velocity-dispersion group or cluster of galaxies including an X-ray confirmed Seyfert 2. The colours...
متن کاملRed supergiants around the obscured open cluster Stephenson 2 , ⋆
Context. Several clusters of red supergiants have been discovered in a small region of the Milky Way close to the base of the ScutumCrux Arm and the tip of the Long Bar. Population synthesis models indicate that they must be very massive to harbour so many supergiants. Amongst these clusters, Stephenson 2, with a core grouping of 26 red supergiants, is a strong candidate to be the most massive ...
متن کاملThe obscured circumnuclear region of the outflow galaxy NGC 3079
Images of the central region of the almost edge-on Sc galaxy NGC 3079 in the J , H and K-bands and in the v = 1→0 S(1) line of molecular hydrogen are presented. The inner few kiloparsecs of NGC 3079 exhibit a large range of nearinfrared colours caused by varying contributions from direct and scattered stellar light, emission from hot dust and extinction gradients. Our results show that interpre...
متن کاملChasing Highly Obscured Qsos in the Cosmos Field
A large population of heavily obscured, Compton-thick AGN is predicted by AGN synthesis models for the cosmic X-ray background and by the “relic” super-massive black-hole mass function measured from local bulges. However, even the deepest X-ray surveys are inefficient to search for these elusive AGN. Alternative selection criteria, combining mid-infrared with near-infrared and optical photometr...
